Those models look great - fantastic subjects. I hope you get enjoyment from them for many years to come.
For me, all the fun is in actually building the things - I have only ever purchased 1 pre-built model - a 1/18 Jaguar XJ-13 (cuz there's no other models made of that unique car).
Don't know if I could ever bring myself to buy a model that someone else had made....
